You can change the web site using apt-cyg mirror <uri> 
or edit /etc/setup/setup.rc /last-mirror/+1 directly.

curl -v sometimes shows when server status codes are returned instead 
of web pages, allowing you to add options to proceed further, step by 
step.
wget -d can also provide more useful information.
Packet analyzers like wireshark etc. can let you see what programs 
like setup are doing (wrong), when compared to wget working correctly.
